Build a mini catapult

This little catapult allows you to launch small objects by storing and releasing potential energy. It also uses Newton’s first law to launch the projectile by creating a force on the spoon that pushes on the projectile, launching it into the air.

Equipment

• Craft popsicle sticks

• Rubber bands

• Plastic spoon

• Small projectiles that fit in the spoon

Method

1. Make a stack of 7 craft popsicle sticks

2. Secure them together with a rubber band at each end

3. Make a stack of two craft sticks

4. Secure the two sticks together with a rubber band at one end

5. Pull the two sticks apart and wedge the stack of 7 sticks between them

6. Secure the plastic spoon to the upper stick with the handle pointing towards the rubber band

7. To launch: place projectile in spoon, push down and release.
